How to open port to server firewall on CentOS 7?

Question

linux

We create a server for minecraft on VPS hosting simplecloud. You need to open port 25565. I enter the command in the terminal:

firewall-cmd --permanent --zone=public --add-port=25565/tcpsudo firewall-cmd --reload

An error is thrown:

usage: see firewall-cmd man page
firewall-cmd: error: unrecognized arguments: firewall-cmd

Answer 1

These are different commands, you need to enter them in turn:

sudo firewall-cmd --permanent --zone=public --add-port=25565/tcp
sudo firewall-cmd --reload

Answer 2

firewall-cmd --permanent --zone=public --add-port=25565/tcpsudo ? firewall-cmd --reload

Do you want to run two commands on the same line? Then separate them &&
